Fabricated from hot-dipped galvanized steel at 24 gauge, this tapped reducer steps down from a 14-inch diameter inlet to a 10-inch diameter outlet. The spiral construction provides structural rigidity along the duct wall, and the tapped ends allow for secure, tool-assisted connection to adjoining duct sections. HVAC installers and sheet metal mechanics use reducers like this when balancing airflow across trunk and branch transitions in residential and light commercial duct systems.\u003c\/p\u003e\n\u003cp\u003eThis reducer is suited for installation in forced-air heating and cooling duct systems where a round spiral duct run changes size between the main trunk line and a branch takeoff. The 14-inch-to-10-inch reduction is common in residential systems where larger supply trunks feed smaller branch runs. Fabricated to ACCA and SMACNA standards, it is appropriate for new construction ductwork and retrofit or replacement applications requiring a code-compliant, galvanized round duct fitting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions from 14-inch diameter to 10-inch diameter in a single spiral round fitting\u003c\/li\u003e\n  \u003cli\u003e24-gauge hot-dipped galvanized steel construction resists corrosion in conditioned and unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003eSpiral seam design adds hoop strength and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eTapped ends accept sheet metal screws for positive mechanical connection\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA applicable standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for round spiral duct systems requiring a concentric reduction from 14-inch to 10-inch diameter round duct.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal mechanic in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air-handling unit and isolate the duct section before fitting installation. Secure tapped ends with sheet metal screws and seal all joints with UL 181-listed mastic or foil tape as required by local code. Verify duct sizing against the ACCA Manual D load calculation before finalizing the transition size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarger End Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmaller End Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot-Dipped Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Thickness\u003c\/strong\u003e: 24 Gauge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Tapped, Spiral, Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOUTHWARK METAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SP58_14X10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284024951090,"sku":"SP58_14X10","price":42.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277989.jpg?v=1781066422","url":"https:\/\/voomisupply.com\/products\/southwark-metal-sp58_14x10-spiral-duct-reducer-14x10-24ga","provider":"Voomi Supply","version":"1.0","type":"link"}
